For some businessmen, a wristwatch is more than a time-telling device. It’s a statement.

„A watch is the greatest icebreaker there is,“ Hamilton Powell, the CEO and founder of Crown & Caliber, an online secondary market for luxury watches, told Business Insider. „In an unfamiliar city, I can approach a complete stranger and with two words eradicate any barriers: ‚Nice watch.'“

„A watch tells people about the type of person you are and what you value,“ Powell added. „The guy who wears a blinged-out gold-diamond Hublot is very different than the guy with a vintage stainless-steel Zenith chronograph.“

With the help of Crown & Caliber’s team of experts, we’ve put together a list of wristwatches worn by the former and current CEOs of some of the world’s most powerful companies.

Here are the timepieces favored by prominent executives, organized from the least to most expensive.

Bill Gates, the cofounder and former CEO of Microsoft

Bill Gates is the cofounder of Microsoft. He became a billionaire at age 31.

In November, he surpassed Jeff Bezos to reclaim his spot as the world’s richest person after two years in second place, according to the Bloomberg Billionaires Index. But Forbes‘ current calculations are different, meaning the current ranking of the world’s wealthiest billionaires is unclear. Bloomberg estimates Gates‘ current net worth to be $110 billion, while Forbes has it at $106.8 billion.

Apple Watch – $399

McMillon is frequently photographed wearing an Apple Watch. The price of the various Apple Watch models starts at $399 on the Apple website. (But, unsurprisingly, it can also be purchased on Walmart’s website for less.)

Jeff Bezos, CEO of Amazon

In November, Bezos was bumped back down to the world’s second-richest person, according to the Bloomberg Billionaires Index. However, Forbes‘ calculations are different, meaning the current ranking of the world’s billionaires is unclear.
